To all whom it concern Be it known that 1, WILLIAM Gnorrnnr Place, a subject of the King of Great Brit- ..ain, residing at Leicester, in the county of' Leicester, England, have invented new and nseful'.Improvements in or Belatingto Braiding-ltlachines, of which the following is .a specification.

front elevation of the machine. Fig. 2 is a sectl'onal'plan taken on the'line a-b of Fig.

, 1. Fig. 3 is a sectional plan taken onthe line cd of Fig. 1. Fig. l is a similar view to Fig. 3 showing the spindles advanced the distance of one position. Fig. 5 1s a iagram representing the path or track of the spindles. Fig. 6 is a di'agrammatical Q plan'view'of showing threads ('of exaggeratedthickness) being twisted together ac cording to this invention to form a cord.

Fig. 7 is a similar view to Fig. 6 showing the reverse plan 2'. e. looking upward from under Fig. 1 is drawn to a smaller scale than the other figures and like parts are designated by the same reference characters throughout the drawings. 7

The machine illustrated comprises (Fig.

1,) a framework consisting of astand 1 and plates 2, 3nd 4: the latter bemg mounted upon the-standby distance bolts or rods 5,

6 and 7 The upper plate 4 supports the take up mechanism (hereinafter described) and the plates 3 and 2 have mounted therein the working heads W. and carrienlheads C. Three Working-heads and three ,'i nter-.

- mediate-,carrier heads are provided; each head being-constructed to accommodate five bobbin spindles. In all fifteen bobbin spin- .dles 8 are used five in each working head as shown in Figs. 2.and'3.,

The heads W; and C consist of a central boss or 'tubular body-part 9 (Fig. 1) having at each end a flange-or disk 10 (Figs. 2 and 3) situated in openings 11 inthe plates 2 and 3 and having in their peripheries radial slots or openings 12 for the reception of the spindles 8. i The heads W and (J are rotatable upon fixed spindles 13 secured in the stand 1 and are driven in the direction of the arrows in Fig. 2 by gears 14 (Fig. 1) which mesh with each other in succession all around the machine and receive motion from a driving gear 15 (Figs. 1 and 3) on a vertical shaft 16 actuated by a clutch l7 and bevel wheels 18, 19 from a main driving shaft 20.

It will be understood that the radial slots 12 in the flanges 10 of each head are in alinc- .ment withe'ach other so that the bobbin spindle 8 which ,enters the maintained upright.

By reference to Figs. 2 and 3 it will be observed that the spindles 8 are prevented from leaving the radial slots 12 of the flanges 10 by the adjacent sides of the openings 11 except at and near thosepoi'nts where the slots will be periphery'of each flange approaches thosev of the adjacent heads. At these localities the peripheries of the flanges 10 are exposed to each other so that when necessary the bobbin spindles 8 can be transferred from the slots of one head to those of the-next adjacent head in the manner shown in F ig.3.

The traverse of the bobbin spindles 8 around the machine will be best undepstood by reference to Figs. 3, 4 and 5. The function of each carrier head C is to car y the bobbin spindles from one working head I to the next, the spindles enteringthe working head on one side thereof, indicated at c Fig. 3, and :ifter being carried around thereby for one complete revolution and part of another, leaving on the side Z opposite to that where they entered. The spindles 8 'on leaving the working heads lV enter the cars rier; heads C and by passing around therein for part of a revolution thereof are transmitted to the next working head. The spindles 8 leave the working heads alternately one after another. For instance in Fig. 3

the spindle 8 is about to leave the head W,

the following spindle 8 will be carried around by the head, the next spindle 8 will leave at the point Z and the spindle just en- I tering from the carrier head C will becarried around. Thls same arrangement of alternation in leaving occurs simultaneously at all the working heads W as will be understood by reference to Fig. 4 where the spindles are shown a little advanced from the position shown in Fig. 3. In the position shown in Fig. 4 the spindles 8 have leftthe working heads 'W and are being transmitted 'by the carrier heads C to the next working spindles at each working head IV are alternately carried around and shunted, the result being that each spindle during its complete revolution around the machine traverses the path diagrammatically represented in Fig. 5. In this figure the positions'of the working heads W and carrying heads C are indicated by the respective reference characters to enable the course of the bobbins to be followed in Figs. 3 and 4. By superposing Figs. 5'and 3 or 5 and at. the course of the bobbins in Figs. 3 and 4 can be clearly traced.

For shunting or switching the bobbin spindles from one head to another a series of dogs or switch points is provided. These members consist of movable switch points 21 (Figs. 3 and 4) and stationary switch points 22. The points 21 are situated on the inside of the circular series of'heads and in the region of the points of exit Z of the working heads IV. Each member 21 is movable about a vertical axis 23 the opposite positions of the switch point being shown in Figs. 3 and 4 respectively. In the position shown in Fig. 3 the switch point 21 intercepts bobbin'spindles as they approach and shunts or transfers them from the 'radial slots of the working head to the corresponding slots in the adjacent carrier head. In the position shown in Fig. 4, the switch point 21 allows the spindlesto be carried around by the working -head past the point of exit without being shunted to the carrier head.

The position of each movable switch point 21 is automatically changed during the operation of the machine and to this endeach of the said members has combined with it or with its axis rod wings 24, 25 adapted to be actuated by the spindles 8 as they pass around in either the working on carrier heads. For instance when the dog or switch point 21 is in the position shown in Fig. 3 the, approaching spindle 8- is shunted from the Working head IV to the carrier head 0 as already described and as this shunted spindle is carried around by the head C it makes cbntact with and moves the wing 24 projecting in its path thereby, as shown in Fig. 4, turning the switch point 21 from the shunting to the clear position so that the following spindle 8 can be carried around by the working head. After )assing the point of exit Z however, the spin le S makes contact with and moves the opposite wing 25 projlecting'in its path thereby turning the switch'point 21 back to the shunting position (Fig. 3-) in time to intercept the next -sp' dle 3 and transfer it from the working head IV to the carrier head Cf Thus each bobbin spindle automatically sets the switch points or dogs 21 to direct the following spindles in the opposite direction.

The stationary switch points 22 are situatedon the outside of the circular series of heads and in the region of the point of exit l of the working heads W (see Figs. 3 and 4.). These switch points are held in the position shown by springs 26 (Fig. 3) which are connected at one end to wings 27 to the axis members 28 of the switch points and at the opposite end to the distance rods or bolts 6. As clearly' shown in Fig. 3 -these stationary switch points intercept the bobbin spindles as they are carried around by the carrier heads C and shunt or transfer them from the radial slots 12of the said heads to the corresponding slots of the adjacent working heads W. Y

The shunting devices or dogs 21, 22 are mounted at opposite ends in-tlle plates 2 and 3 as shown in Fig. 1. a switch point in each case beingprovided at the top andtwisting or turning around during their traverse the plate 3 has upstanding rims 29- (Fig. 2) surrounding the openings 11.

These prevent the bobbins turning in one direction while the bosses 30 of the heads W and G prevent them turning in the other direction. Guides 31 are fixed to the plate 3 to prevent the spindles twisting during the time of their transferrence from one working head to the next. I I V The threads 32 (Fig. 1)-from, the'bobbin spindles 8' are drawn up and as they are plaited together the resultant cord or the like 33 guided by a pulley 34 passes up to and around a frictioni'drum 35 and from thence through a guide so to a bobbin 37 upon which it is wound. The whole of the take up mechanism is mounted upon a wheel 38 adapted to rotate upon a boss 39 on the top plate 4. The wheel 33 is driven by a pinion -10 on the lieforementioned vertical driving: shaft in thespeed of rotation of said wheel being uniform with that of the weasel facture. "The take up drum is driven by a worm-gear l-l which is intermittently ac- 'tuatedby the engagement of a gear wheel 4-2- with a fixed toothed segment 43 as the mechanisn'i revolves.

The bobbin 37 is rotated from the shaft 44 by a belt i a The bobbin spindles are preferably of the i usual well known construction provided with thread con-trolls dropping weight for automatically stopping the machinev when any thread breaks; The dropped Weight of any spindle makes contactwith and moves a plate at (Fig. 3) attached to slide bar 4?,

. movement of the latter releasing a vertically slid'able pin 48 (Figs; 1 and 3) connected with a horizontal lever 49 fulcrumed at 50. Upon release of the pin 48 the said lever is moved upward by the pressure of a blade spring 51 thereunder (shown by dotted lines in Fig. 3) and disconnects the; clutch 17 to stop the machine. The end of the slide bar adjacent the pin 48 is beveled on; the underside or is suitably formed to depress the said pin when the bar is pushed inward thereby through the medium of the lever 49 putting the clutch into action to start the machine.

It is found simplest as regards construction to arrange the shafts or spindles 13 of the heads W and O vertically, the bobbin spindles likewise having a vertical disposition. The said shafts may, however, if desired, be disposed at an inclination to the vertical, theirp. upper ends leaning toward each other. l' ltthis convergent arrangement is adopted, thelbobbin spindles in opposite heads will likewise assume and work in an inclined position as will be understood.

While the hereindescribed number of working heads is found convenient and suit able it is to be understood that a greater number of such heads may be employed with, of course, a corresponding increase in the number of intermediate carrier heads,

the bobbin spindles being transferred from one working head to another as previously described. Also the number of bobbin spindles carried by each working head may be varied so long as an odd number are used. For instance each working head may have accommodation for three, five, seven, nine, eleven or any higher'odd number of spindles within reason the spindles leaving the'heads in alternation as hereinbefore described.

The result of the herein-before described motions of the bobbin spindles as regards the formation of the cord will be best seen by reference to Figs. 6 and 7 the numbers of working hedds and spindles employed being respectively three and fifteen. For the sake of clearness, in these figures the work.- ing heads 'W and carrier heads C are represented by dotted line circles only, the direccated by arrows thereon. .To enable the intertwining threads to'be mdne readily dis tinguished, the threads of the spindles which are being transferred by the carrier heads are shaded. Bearing in mind the aforesaid principle of operation 2'. e. the spindles leave each working head in alternation, it will be understood that in the po sition shown in Figs. 6 and 7, the spindles 1* having left the working heads, of the following spindles 2 will be carl ied around by the working heads, 3 will leave, at will be carried around, and 5? will leave. result of this is that each threadis carried before its spindle leaves the working head to be wrapped or twisted around the next two alternate threads. vFor instance in the diagrams it will be seen that the thread of spindle 1 is wrapped around the threads of spindles 3 and 5- the same result being brbught about each working head: The number of following threads engaged by each thread will depend upon the number of spindlesin each working head. For instance-by reason of'the employment of five spindles in each head as shown, each thread engages the two alternate following threads. If however, three spindles were used in each head each thread would wrap .,around the next alternate thread; if each head had'seven spindles, each thread would wrap around the following three alternate threads. A thread or cord formed according to the method of operating the present machine may therefore be'said to be characterized by the fact that each of its threads is wrapped or twisted around the next alternate thread or threads and passes across the interior from one exterior point of the cord to another thereby compacting the cord and forming an integral approximately solid core. The combined effect of the engagement of each thread with one or more of the following alternate threads and the carry ing of said thread across from a point on the circle to an'opposite point is to draw 'almost entirely filling up the said center.

The number of .times each thread will -appear on the surface of the cord during a complete revolution of the bobbins depends of course upon the number of working heads employed, With three working heads wherein each bobbin spindle is carried around twice ashereindescribed, each thread will show six times on the surface; with four heads each thread would appear eight times, and so on;

hen the improved plaited or braided cord is to be used as fishing line it may be subsequently treated with shellac and linseed oil. j

\ What I claim then is:

1. A braiding or cord making machine The dles, and a series of devices operating automatically to select the bobbin. spindles in alternation 1n the working heads and shunt the selected spindles from the working heads to the carrier lliltlS, the arrangement beingsuch that each spindle is carried around more than once by each working head before being selected and shunted. for the purpose described.

2. A braiding or cord making machine comprising, in combination a series of bobbin spindles, a plurality of working heads. a corresponding series of intermediate earrier heads, a series of stationary switch points arranged to intercept the traveling spindles and transfer them from the carrier heads to the working heads, a series of pivoted switch points adapted to intercept the traveling spindles .and transfer -'them from the working heads to the carrier heads, and wings on said pivoted switch name to this specification-inthe presence of two subscribing witnesses.
